Abstract:
Introducing buckling pattern into straight-walled lattice structure, a novel buckling inspired lattice meta-structure (BILM) was designed and fabricated using polylactic acid (PLA) by three-dimensional (3D) printing technology. The square lattice structure with positive Poisson’s ratio (PPR) is transformed into negative Poisson’s ratio (NPR) structure by buckling induction. Curved struts decrease the maximum strain, prohibit strut fracture, increase strut contact and induce ductile bending deformation.
